Research Themes

Cognitive and Behavioural Neuroscience

Systems and Computational Neuroscience


Delusions are odd beliefs. They accompany many psychiatric illnesses, notably schizophrenia. A major challenge is to understand delusions in terms of changes in brain function. I attempted to meet this challenge by investigating the neural basis of human associative learning and belief formation, relating these processes to the formation of delusional beliefs. My findings have shaped the development of a novel mechanistic model of delusion formation.

I am currently a visiting fellow at Yale Medical School, Department of Psychiatry in the laboratories of Professor Jane Taylor and Professor John Krystal
